Thread: copy command and array of composite types?

I'm using PostgreSQL 8.3.1.

 

I've created the following composite type:

 

CREATE TYPE expression_event_type AS (
event_id varchar(10),
expr_indices smallint[]
);

 

which is used with the following table definition:

 

CREATE TABLE boolean_expr_table(
expr_id smallint PRIMARY KEY,
expr_name varchar(100) NOT NULL,
expression varchar(256) NOT NULL,
event_indices expression_event_type[] NOT NULL,
true_cases smallint[] NOT NULL
);

 

Question: What is the correct way to load the event_indices column using the copy command and a external file?

 

I've tried: {(1,{1,2,3})} without success.
